Disease resistance
Suzuka has an outstanding disease resistance profile, including resistance to both barley mild and barley yellow mosaic virus and is the only variety with a 9 rating for Rhynchosporium.

Fungicide use
- T0 - Only needed in extremely high risk disease pressure situations.
- T1 - T1 timing is the key for protecting the canopy during the plants' main spring growth period, as during this time competition from disease reduces the development of potential grain sites. The use of Kayak + a triazole or strobilurin based product gives a broad-spectrum of disease control. Triazole should be added in a curative situation or where the crop is showing high levels of brown rust.
- T2 - T2 application is to protect green leaf and prolong grain filling as premature senescence caused by disease and abiotic leaf spotting reduces yield and increases loss through screenings and specific weight. Bravo has been demonstrated to have affect against biotic and abiotic leaf spotting, good disease control and prolonged green leaf retention.
Core fungicide programme
- T0 - Kayak + Tern (only needed in high risk disease pressure situations)
- T1 - Kayak + Triazole or Strobilurin
- T2 - Amistar Opti + Triazole
Note: Amistar Opti is a co-formulation containing azoxystrobin and chlorothalonil (Bravo).
Agronomic information

Recommended sowing rate
Seed rates are dependent on soil conditions at the time of drilling: the more difficult the environment, the higher the seed rate must be to compensate for potential plant loss. The table below shows the number of seeds per square metre that should be planted in good conditions.
The table above should always be used in conjunction with thousand-grain weight of the seed to calculate the seed rate.
Nitrogen application
Suzuka has good lodging resistance, so will benefit from high amounts of nitrogen, however a managed approach according to site fertility needs to be taken into account.
In a second cereal situation, NFC recommend 170kg/ha N with a split dressing of 50% mid-March, and 50% during mid-April.
PGRs
Suzuka has very good lodging resistance, but PGR’s can be used to promote root development and even the crop.
NFC recommend the use of Moddus plus a chlormequat-based product at GS31.
A second PGR would only be needed in very lush crops or very fertile sites.
Core guidelines
- GS31-32 – Moddus 0.2 lt/ha + chlormequat 1.25 lt/ha at onset of stem extension.
- GS37 – Moddus 0.3 lt/ha or ethephon + mepiquat chloride 0.1 lt/ha (in high risk situations).
Grain quality
Suzuka has excellent grain characteristics:
Specific weight: 69.9 kg/hl
Screenings % through 2.25mm: 3.4
Screenings % through 2.5mm: 9.0
